Tyne
a river of England, formed by the junction near Hexham of the North Tyne, which rises in the Cheviots, on the borders of Roxburgh, and the South Tyne, which rises at Tynehead Fell, in the extreme E. of Cumberland. The united stream divides the counties of Durham and Northumberland, passes the ports of Newcastle, Jarrow, North and South Shields, and enters the sea at Tynemouth after a course from Hexham of nearly 30 miles. The Tyne has, since 1854, been the subject of large engineering operations, consisting of extensive dredging, the construction of piers at its mouth, the formation of large docks, and the building of a swing bridge at Newcastle. Thus from the sea to Scotswood suspension bridge, a distance of about 10 miles, the river is navigable for large vessels, and the trade on the river, chiefly in coal, has immensely increased.
